Saving space

In modern indoor commercial planting, space, yield, and environmental control are indispensable. The ceiling mounted dehumidifier is an efficient solution designed for professional growers. Unlike traditional floor-standing machines, ceiling dehumidifiers are installed on the top structure and do not occupy any valuable planting area, allowing every inch of space to be used to increase production. For planting rooms that use vertical planting racks, multi-layer systems, or high-density layouts, this design advantage is particularly evident.

Keep a stable environment

In addition to saving space, ceiling dehumidifiers can also provide more uniform air circulation. Due to the principle of condensation dehumidification requiring continuous air exchange, top air supply can effectively reduce wet areas, dead corners, and moisture storage areas, improve indoor microclimate, and maintain more consistent and controllable temperature and humidity throughout the room. Stable humidity helps maintain the optimal VPD range, promotes photosynthesis, reduces fungal spore growth, and provides plants with a healthier and more predictable environment throughout their entire growth cycle.

Smart control

The grow room dehumidifier is far away from the ground, and the control board on the body is rarely used. For the convenience of controlling the machine, our dehumidifier's control system has specially connected control signals, such as Trolmaster, Honeywell controller, and K30 control board (manufactured by Preair dehumidifier factory). By using the above controller, remote control can be achieved, real-time monitoring can be carried out, and historical data can be queried to scientifically adjust indoor humidity based on plant growth trends and VPD.

Other features

More importantly, ceiling dehumidifiers typically have stronger drainage capacity, higher durability, and lower maintenance requirements, making them ideal for commercial planting facilities that operate for long periods of time every day. Whether it's cannabis cultivation, vegetable factories, sprout production, or other controlled environment agriculture (CEA) scenarios, ceiling dehumidifiers can provide professional-level humidity management.

Recommended models for commercial cultivation

The PRO230 ceiling dehumidifier is particularly suitable for indoor commercial planting scenarios. Compared with floor standing dehumidifiers, it is installed on the ceiling or top structure, does not occupy any planting area, does not block light, and avoids direct blowing of equipment that affects plants. The top layout also allows for more uniform air circulation, which is beneficial for controlling VPD, reducing mold risk, and maintaining a stable temperature and humidity environment. It is very suitable for medium to large planting rooms, dense planting rack systems, and vertical farms. The capacity of the PRO230 is 230PPD @26.7℃/60%RH. There are higher-capacity dehumidifiers of the same series, PRO300, PRO330, and PRO500. Tell Preair the information about your grow rooms, and we will provide a detailed dehumidification solution.
